Flavanone 7-O-beta-glucosyltransferase

In enzymology, a flavanone 7-O-beta-glucosyltransferase (EC 2.4.1.185) is an enzyme that catalyzes the chemical reaction

UDP-glucose + a flavanone ${\displaystyle \rightleftharpoons }$ UDP + a flavanone 7-O-beta-D-glucoside

Thus, the two substrates of this enzyme are UDP-glucose and flavanone, whereas its two products are UDP and .

This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:flavanone 7-O-beta-D-glucosyltransferase. Other names in common use include uridine diphosphoglucose-flavanone 7-O-glucosyltransferase, naringenin 7-O-glucosyltransferase, and hesperetin 7-O-glucosyl-transferase.
